Waters 2465 Electrochemical Detector

The Waters 2465 Electrochemical Detector combines sensitivity, reliability and simplicity for HPLC electrochemical detection. Its versatile detection modes are ideally suited for analyzing a wide range of compounds.

The Waters 2465 Electrochemical Detector’s multiple flow-cell configuration combines working and reference electrode designs to minimize cost and enhance flexibility. The flow cell accommodates several reference electrodes: ISAAC; traditional salt-bridge design, which limits air bubble formation; and Hy-Ref, which is ideal for carbohydrate analysis and is compatible with extreme mobile phases.

The Waters 2465 Electrochemical Detector is designed for ultra-trace analysis in standard and microbore Alliance® HPLC based, Empower™ Software controlled applications.

Features:
• Multiple detection modes, including direct current, pulsed amperometric, and scanning
• Easier maintenance with front-mounted flow cell for simple cleaning and assembly
• Stabilized temperature for better accuracy with the integral flow cell and column heater compartment
• Faraday-shielded oven with thermal operating stability and reduced noise and drift characteristics
